| Answer | Question |
|---|---|
| the force put on a given area by the weight of the air around it | air pressure |
| a violent whirling wind that moves across the ground in a narrow path; strongest winds | tornado |
| a very large, swirling storm with a very low pressure in the center which causes major destruction due to its storm surge; fueled by warm ocean temperatures | hurricane |
| storm with very low temperatures (<20 degrees Fahrenheit) and winds that are > 35 mph. Large amounts of snowfall decrease visibility. | blizzard |
| the most common severe storm, formed in cumulonimbus clouds and severe lightning is present | thunderstorm |
| a high-altitude cloud made of ice crystals; thin and wispy; brings no precipitation; generally precipitation can come in a day or two | cirrus clouds |
| a cloud that forms a blanket-like layer across the sky, lowest clouds | stratus clouds |
| a puffy cloud that appears to rise up from a flat bottom, middle layer clouds, fair weather | cumulus clouds |
| large thunderstorm clouds; often called thunderheads; produce large amounts of precipitation | cumulonimbus clouds |
| a device that indicates wind direction (N, S, E, W) | wind vane |
| a cylinder tube that measures rainfall (inches or cm) | rain gauge |
| an instrument that measures wind speed (mph or kph) | anemometer |
| a device for measuring air pressure (inches or millibars) | barometer |
| an instrument used to measure air temperature (Fahrenheit or Celsius) | thermometer |
| a device used to measure humidity (percentage 0-100) | hygrometer |
| an instrument used to measure snowfall | ruler/yardstick |
| the amount of water vapor in the air | humidity |
| 14.7 pounds per square inch | average pressure felt per square inch |
| high/low | Air molecules want to move from areas of _______ pressure to areas of _______ pressure. |
| It is more dense than warm air. | Why does cold air weigh more than warm air? |
| FAST | Low pressure is __________ moving air or water. |
| clouds that bring precipitation. | The word nimbo or nimbus means.... |
| Less dense because air molecules have more energy and they are more spread out...causing the air to be lighter/less dense. | Is air more or less dense around the equator? |
| low | A thunderstorm is an example of a ____________ pressure system. |
| high | A sunny day is an example of a ______________ pressure system. |
| the continuous movement of water on Earth | hydrological cycle |
| the process where water vapor turns into a liquid; forms clouds; heat energy is lost | condensation |
| the process where water changes from a liquid to a gas (vapor); heat energy is gained | evaporation |
| water that seeps/soaks into earth's surface | infiltration |
| the process where water returns to the earth in the form of rain, snow, sleet, or hail | precipitation |
| the process where water is slowly released from plant life into the atmosphere | transpiration |
| water that flows over the surface of the earth | runoff |
